Patent DE-2943361-A1 (DE)
Title: Inlet valve for IC engine - has sleeve operated by differential pressure to prevent exhaust flowing back into inlet
Inventor: BURSA FERDINAND
IPC: F01L1/28
Filed: 1979-10-26
Abstract: The valve has a shaft (1) with a mushroom head (2). The upper surface of the head closes on a valve seat (3) in the cylinder head. A profiled sleeve (4,5) sits loosely on the bottom of the shaft and top of the head. Its outer periphery closes on the same valve seat as the valve head. The valve is operated by the camshaft in the conventional manner. The sleeve is operated by the pressure difference across it. It keeps the inlet closed after the valve opens so long as there are exhaust gases in the cylinder at a pressure higher than that in the inlet passage.

Title: Moisture content control for granular feed - by measuring press reaction force for press plunger
Inventor: SEWING WALTER DIPL ING
IPC: B02C15/14
Filed: 1979-11-08
Abstract: Granular feed material, e.g. slack and fine coal for gasification under pressure, is pressed into strands in the die channels of an edge runner mill. Its parameters are determined by placing a sample ahead of the mill into the bore of a slider and by pressing the sample by a plunger into a die. The force of reaction on the plunger or on the die is measured and is used to control the moisture content as the most important parameter govering the suitability of the material for agglomeration. This produces quick and accurate figures for the moisture content by uncomplicated apparatus which can form a part of an automatic control loop.

Title: Heat pump changeover system for defrosting - opens valve parallel to expansion valve before operating changeover valve
Inventor: PETZ MANFRED
IPC: F25B47/02
Filed: 1980-06-25
Abstract: The changeover system is for a heat pump with evaporator, compressor, condenser, expansion valve and changeover valve. The latter converts the evaporator used when heating into a condenser and the condenser into an evaporator, being particularly for defrosting the evaporator. At a set time before operation of the changeover valve (5) a valve (11) connected in parallel with the expansion valve (12) is opened, this time being so calculated that the liquid refrigerating medium from the condenser (6) is transferred into the evaporator (1) under the effect of the pressure difference between the suction and discharge sides of the compressor (4). The changeover valve is operated when this action is complete.

Title: Feeding and unloading apparatus and work carriers at assembly and machining stations
Inventor: KESSLER KURT
IPC: B65G47/74
Filed: 1981-01-20
Abstract: The loading of several machine tools (2) with the workpieces (20), accurately mounted on metal work carriers (7) (pallets), by means of rail-borne transport vehicles (6) is difficult when the machine tools (2) are at different distances from the rail guide (5) for the transport vehicles (6). In order to overcome this difficulty, one guide (8) each for transfer vehicles (9) crosses the guide (5) for the transport vehicle (6). The guide (8) is allocated to the individual machine tool (2) and is at a more accurate distance from it. The transfer vehicle (9) has parallelogram-like links (10, 11) which lift the tool carrier (7) from the transport vehicle (6) when the latter is passing and subsequently lower the tool carrier (7) onto the machine tool (2). <IMAGE>

Title: Apparatus for conveying and collecting a plurality of rows of ceramic blanks arranged on blank supports
Inventor: MIDDENDORF ALBERT
IPC: B65G49/08
Filed: 1981-03-12
Abstract: An apparatus for conveying and collecting a plurality of rows of ceramic blanks, especially bricks, arranged on blank supports consists of a transverse conveyor, an elevator in which a stack of superposed blank supports is formed, and a collecting rack which has a stationary rack and a movable storage frame remaining on the stationary rack. The storage frame is provided with a plurality of lateral rests for the blank supports, arranged at a distance one above the other. The rests project in a self-supporting manner beyond the end face of the storage frame. The rests can be moved into the elevator and are designed sufficiently long to be able to receive a plurality of blank stacks in succession. In order to make it possible to lift off the transverse conveyor the last blank support introduced into a stack accumulated in the elevator, the bottommost rests of the storage frame are designed to be pivotable. The pivoting of the bottommost rests is undertaken by a lifting apparatus arranged in the end region of the transverse conveyor.

Title: Method and arrangement for adjusting the discriminator of an image evaluating device
Inventor: BRAEUER REINHARD DIPL ING
IPC: G06V10/28
Filed: 1981-03-30
Abstract: Image evaluating devices contain discriminators which are supplied with the video signal generated by a video scanning device. For it to be possible to recognise predetermined structures contained in the images to be evaluated, even under different illumination of the individual images, the discriminator is successively adjusted to different response ranges during one scanning period each. With each discriminator adjustment, a check is made as to whether the output signal of the discriminator meets criteria which correspond to the predetermined structures. The image is evaluated only when these criteria are met. The main application of the invention is television systems for automatic image evaluation. <IMAGE>

Title: Internal combustion engine
Inventor: SOELCH ROLAND
IPC: F02G5/02
Filed: 1981-07-24
Abstract: In internal combustion engines large energy losses occur due to waste heat, only a fraction of the waste heat having a high temperature. The object of the invention is achieved according to the size of an internal combustion engine by measures as described under section "a" or section "a and b".   a) Improvement of the efficiency by an increase of the heat potential of the working process gases inside a working process chamber by a reduction of the temperature differentials between hot working process gases and the inner surface of the working process chamber by means of a reduction of the heat transfer per unit area through a wall of the working process chamber, for example by means of thermal insulation, a piston moving free of contact in the working process chamber, which piston is guided and sealed in an area adjacent to the working process chamber, which has a relatively low operating temperature. b) Use of the larger quantity of waste heat in the exhaust gases as a result of measure a) for additional energy conversion.
